If you didn't have commas separating your arguments, the method would have no way of telling them apart, and would read it as one long argument.
The commas help to separate ideas, just as in regular language.

Quotation marks, whether single or double, are used to create a data type called a "string", which is text. If you need some more refreshing on syntax and punctuation and their uses in code, I highly recommend going back to basic, beginner videos and rewatching until this information sinks in and sticks. You will have a very difficult time moving forward if you have yet to learn these core principles and ways of doing things. They are absolutely necessary for writing any sort of code, so you need to make sure you understand them before progressing.
